Ensure that the ARM compiler provides macros that can be used to differentiate between the HardFP and SoftFP ABIs.

This is targeted at 4.4 and 4.5.

We should use the ARM extensions to be compatible with the proposed "ARM C language
extension spec" (rather than inventing new macros).
The macro for this is __ARM_PCS_VFP__

Can you provide a link to this spec?

Alternatively, a bit more info about how this macro is expected to be used/set, and what to do for the other ABIs would be good enough.
